[Xen-users] Problem with bridge eth0. DomU access to Dom0 but doesn't access to Internet

["Diaz Corchero, Miguel Angel" <miguelangel.diaz@xxxxxxxxx>]

Hello.

I have a problem with my bridge.
My bridge eth0 is up, and if i do a ping from dom0 to domU it's successful. Too, if i do a ping from domU to dom0 it's successful, but i can't do a ping from domU to another machine into Lan.

Thanks in advance.


Below I have written the output of comands and SOs installed in Doms


Dom0 is Centos5.2 x64 with Xen3.2
DomU is Centos5.2 x64
The brctl command returns this:
bridge name     bridge id               STP enabled     interfaces
eth0            8000.0014221e75c7       no              vif2.0
                                                        peth0
And ifconfig returns this:
